Figures 4 and 5 illustrate detailed configurations of the lifting control unit (100) according to the present invention.

[Assembly process]

In the elevation control unit (100), the pressure control unit (50) is installed in a control unit installation groove (100a) formed inside the pressure control unit (50) to adjust the height of the angle control unit (42).

The control unit sliding rail (110) is installed in the control unit installation groove (100a).

At this time, the control unit sliding rail (110) is provided in a shape with an open center in the shape of the letter ‘ㅁ’ based on the flat surface.

In addition, the adjustment unit sliding rail (110) is arranged in a vertical direction so that both sides of the angle adjustment unit (42) and the elevation adjustment protrusion (140) can come into contact.

In particular, a rail groove (111) is formed as a through hole along the inner length direction of the control unit sliding rail (110).

The control section rail movement gear (180) is fastened so as to be able to rotate along the rail home (111).

A lifting control gear (130) is rotatably arranged in the open central portion of the control unit sliding rail (110).

At this time, a lift control projection (140) is formed protruding along the outer circumference of the lift control gear (130).

Next, the gear support shaft (120) passes through the center of the lifting control gear (130) and is fastened to both sides of the control unit sliding rail (110).

One side of the shaft support member (150) is integrally fixed to both ends of the gear support shaft (120).

At this time, the rotating part installation frame (210) is placed in a vertical direction.

One side of the rotating part diagonal frame (220) is fixed to both upper sides of the rotating part installation frame (210).

Next, the rotating part diagonal frame (220) is formed in an increasingly diagonal shape from the rotating part installation frame (210).

Since the rotating part diagonal frame (220) is formed in a diagonal shape, the vibration generating part (300) can be arranged diagonally, thereby allowing the gear rotating ball (250) and the rotating part rotation frame (240) to perform a seesaw motion.

The frame rotation shaft (230) penetrates and inserts into the lower part of the rotation installation frame (210) in the central part of the rotation frame (240).

The frame rotation axis (230) can support the rotation of the rotating part rotation frame (240).

Next, gear rotation balls (250) are fixed to both ends of the rotation frame (240).

The gear rotation ball (250) can induce rotation of the rail movement gear (180) by striking the outer periphery of the rail movement gear (180) by the rotation of the rotation part rotation frame (240).

In the vibration generating unit (300), the generating unit installation groove (300a) formed at regular intervals in the rotating unit diagonal frame (220) is installed to vibrate the gear rotating ball (250) to induce rotation of the gear rotating ball (250) and the rotating unit rotation frame (240).

The generator installation body (310) is fixed to the generator installation groove (300a).

Next, the absent piston shaft (360) is inserted into the absent piston cylinder (350) so as to enable piston movement.

Next, the upper part of the piston shaft (360) is fixed to the lower center of the striking member (370).

The striking member (370) can raise and lower the protrusion support shaft (320) by striking the striking surface (321).

[Example]

By control, the regulating part rail moving gear (180) rotates and moves vertically along the shape of the regulating part sliding rail (110).

The gear support member (170), the auxiliary rotation ball (160), the shaft support member (150) and the gear support shaft (120) connected to the adjustment section rail moving gear (180) move integrally with the adjustment section rail moving gear (180).

At this time, the gear support member (170), the member rotation ball (160), the shaft support member (150), the gear support shaft (120), and the elevation control gear (130) rotate as one unit by the rotation of the control member rail movement gear (180).

By rotating the elevation control gear (130), the elevation control projection (140) strikes the wedge shape formed on both sides of the height adjustment part to adjust the height of the height adjustment part.

The vibration generating unit (300) is operated by control to rotate the regulating unit rail moving gear (180) to vibrate the gear rotation ball (250).

The rotation frame (240) of the rotating part is supported on the frame rotation shaft (230) by the force caused by the vibration of the gear rotation ball (250) and rotates like a seesaw.

The vibration of the gear rotation ball (250) is transmitted to the outer circumference of the control rail movement gear (180), causing the control rail movement gear (180) to rotate.

For the operation of the vibration generating unit (300), the absent piston shaft (360) performs piston movement from the absent piston cylinder (350) by control.

By the piston movement of the piston shafts (360) facing each other diagonally, the striking member (370) strikes the entire striking surface (321) simultaneously in a diagonal direction, thereby moving the projection support shaft (320) in a vertical direction.

The movement of the projection support shaft (320) causes the generation projection (330) to come into contact with the gear rotation ball (250), thereby vibrating the gear rotation ball (250).

At this time, the gear rotation ball (250) induces the rotation of the control rail movement gear (180) by rotating the rotation frame (240) so that the gear rotation ball (250) strikes the outer peripheral portion of the control rail movement gear (180) in an oblique direction, and the control rail movement gear (180) can rotate due to the impact.

Next, the generating part protrusion (330) and the protrusion support shaft (320) perform repetitive movements by the elastic force of the generating part maintenance spring (340), and can alleviate excessive shock and external shock caused by vibration.

Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above, and various modifications may be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims.
